'30 Rock' celebrates Leap Day

NBC's comedy series embraces this year's extra day with Leap Day William.

Feb. 29 is Leap Day, a special moment in time when an extra day is added to the calendar to keep things "coordinated with the sun's apparent position." I'd love to explain it in more detail to you, but honestly you're likely more interested in how "30 Rock" interprets the event.

The NBC comedy series is used to putting a hilarious spin on obscure holidays and Feb. 29 is no exception. In an exclusive preview given to Entertainment Weekly, we see page Kenneth dressed as Leap Day William, handing out candy to the employees.

When a bewildered Liz Lemon (Tina Fey) asks who Leap Day William is, Kenneth replies, "He lives in the Mariana trench and emerges every four years to trade children's tears for candy." Naturally. Check out the clip below.
